It didn't seem to cog bad on the bench but the turbine had fits.I removed them like they were just sitting on the rotor.Maybe the iron used to help the bond got sucked around to the point that it weakens the stuff.I'm sure the stuff never thought it had to adhere magnets.

 This epoxy uses kevlar tiny fibers.

 I tested a long cure(waterproof)epoxy and busted the mag trying to remove it.So i guess i was lucky i used jb on the motor.
